The Schuller laboratory investigates the structure and function of macromolecular assemblies using structural biology, biochemistry and molecular biology. Our laboratory specializes in cryoEM single particle analysis. This method enables us not only to determine high-resolution structures of membrane-bound multiprotein complexes, but also to uncover their molecular dynamics, which is essential for understanding their biomolecular function. We are particularly interested. in biological systems that are responsible for biological carbon fixation, biological energy conversion and transport. Current topics of research are: (I) Prokaryotic Carbon concentration mechanism. (II) Thylakoid biogenesis and maintenance. (III) Carbon fixation and energy conservation in chemolithoautotrophic metabolism.
These biochemical pathways hold a wealth of opportunities for synthetic biology approaches that could be used to create improved microbes for the production of chemical compounds, to produce solar fuels and to sequester CO2 to combat global warming.
